Given I want to snatch a cheap item with defined preferred stats. Can I hit the Search button over and over again, or do I retrieve a cached version?
If there is a caching mechanism: Does changing stat values/types or max buyout slightly force a non cached request? What is being cached? When does the cache expire?
Is there a throttling mechanism in place, do they slow down a client which is constantly requesting results?
The reason behind this question is that cheap items will be bought out seconds later, and you really need to be very quick to get the item.
I know that only a Blizzard system designer can answer this question with 100 percent certainty, but I am interested in your observations, for me its a black box right now.
Own observation: The Windows Resource Monitor shows network traffic for Diablo III.exe each time I hit the search button, implying there's no local caching going on.
